With Attorney General William Barr’s release of the Mueller report, debate about Donald Trump will rage in Congress and comments sections, and culminate in the 2020 presidential election.

Special counsel Robert S. Mueller III’s long-awaited report, all but a relatively small redacted portion of it, has finally been made public.

But with Democratic candidates — and at least one other Republican — lining up to challenge President Donald Trump, how many voters will read the entire report’s 448 pages and 2,375 footnotes? And how many will rely on tweets denigrating it or Attorney General William Barr’s summary downplaying it or pick-a-pundit’s instant armchair analysis?

In a way, the Mueller report is the modern equivalent of the Zapruder film but with a much smaller audience and probably less staying power: It’s open to interpretation. The best way to come to your own conclusions is to spend as much time as you like with it, then move on. Plenty of others will remain plenty preoccupied by it, starting with House Democrats, who now face a choice: Focus more on Mueller’s investigation or on the 2020 election.

The San Diego Union-Tribune Editorial Board’s thinking is that Congress should close the loop on its open questions about the Mueller report but not drag this out. There are real issues the country needs to address — immigration, health care, income equality, job security, etc. — and the United States is now closer to the 2020 election than it is to the 2016 election. Californians will start casting ballots in their party’s primaries in 10 months. Let’s let the public decide whether it wants to keep this president or remove him from office. Let’s urge the public to redirect its emotions into the election.

But first, let’s focus on three main points made abundantly clear by Mueller’s investigation.

One, Russia clearly interfered with the 2016 election, and the U.S. president undermined the findings of his intelligence community after a briefing in January 2017 that detailed the meddling. Mueller reported that the Russian government interfered in the 2016 election “in sweeping and systematic fashion” via a torrent of social media posts favoring Trump and by hacking into the Clinton campaign. A Russian entity directly served at least 29 million people content in their news feeds via nearly 80,000 posts over two years — posts that may have reached 126 million people — a deception that undermined both U.S. laws and the U.S. election, despite Trump pooh-poohing the idea. Congress and the president need to ensure there are safeguards to thwart such an effort in the 2020 election.

Two, the Trump campaign had numerous contacts with Russian agents, just not in a way to prove collusion in court. But the president repeatedly sought to squelch aspects of Mueller’s investigation by asking aides to take actions to pressure people. Those aides — from White House Counsel Don McGahn to former campaign manager Corey Lewandowski — refused. The system worked, barely.

Three, Barr is the president’s attorney general, not, it seems, the people’s. Trump appointed him. Trump can fire him. And Barr’s four-page summary about a report 112 times as long wasn’t nearly as clear-cut as Barr let on or as the president tweeted at the time. It was not a “complete and total exoneration.” On the contrary, the report said investigators found no evidence of collusion but lacked “confidence” to say Trump “clearly did not commit obstruction of justice.” Now we are where we are.

Debate about Trump will rage in Congress and comments sections. Mueller may testify before Congress, fueling more. But it will culminate in the November 2020 presidential election. Americans — from Mueller to the 535 members of Congress to the tens of millions of registered voters in the U.S. — have a say in what happens next. That’s as it should be. Because Americans deserve presidents who will put the country’s interests before their own.
